Abstract
In 2014, high mortality was observed in olive flounder (Paralichthys olivaceus) during experimental infection. Diseased fish did not show any outward clinical signs, but numerous fungal hyphae were detected in the gills. No parasites or bacteria were isolated from the diseased fish. A high mortality rate (100%) resulted when cohabitation with fungi-infected fish were applied to healthy fish. The affected fish exhibited sever fungi infection in the gills. Histopathological examination revealed numerous fungal hyphae and mycelium around gill filament, lamellar and racker. These results suggest that the fungi may be related with the mortality of olive flounder.
